The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable BV FH40 marine steel material steel products and wholehearted service. The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the market and has strong competitiveness.
The advantages of BV FH40 marine steel material, steel plate produced from coil: price is cheap and length can be freely determined; transportation is convenient, no need to consider according to the size of steel plate; cutting is convenient, according to the actual needs of steel plate size cutting, and finally can effectively save materials. The disadvantage of steel plate produced from coil: there will be great welding deformation during welding, which is difficult to adjust. Therefore, the steel plate produced from coil can not be used for parts with high requirements on appearance quality.
The difference between Q195 steel and 20# steel: BV FH40 marine steel material, Q195 steel is ordinary carbon structural steel, in which alloy elements are not specially added, and it is mainly used for construction and engineering structures. Q195 steel has low carbon and manganese content, low strength, good plasticity, high toughness, and good process performance and weldability. 20# steel is high-quality carbon structural steel. Alloy elements are not specially added to 20# steel, and it is mainly used in the manufacture of machine structures, and the amount of use is particularly large. 20# steel has higher strength than Q195 steel, good weldability, no temper brittleness, and its workability can be improved by water quenching.
"The production method of seamless steel pipe can be roughly divided into cross rolling method (menesmann method) and extrusion method. The cross rolling method (menesmann method) is to pierce the tube blank with the cross roll first, and then extend it with the rolling mill. This method is fast in production, but requires high machinability of tube blank. It is mainly suitable for producing carbon steel and low alloy steel tube, BV FH40 marine steel material tube.The extrusion method is to pierce the billet or ingot with a piercer, and then extrude it into a steel tube with an extruder. This method is less efficient than the cross rolling method and is suitable for the production of high-strength alloy steel tubes."
JIS g3101:2004 ss540 structural steel angle contains 0.30% carbon and 1.60% manganese, which greatly improves the strength of steel. Compared with BV FH40 marine steel material SS400 and ss490, ss540 has higher strength with yield strength of 400MPa and tensile strength of 540Mpa. High strength makes it popular in applications that require strength but weight is a problem.
